Stochastic Peak Age of Information Guarantee for Cooperative Sensing in Internet of Everything

IEEE Internet of Things Journal, 2023
This article focuses on the service freshness guarantee for cooperative sensing in the Internet of Everything. Specifically, the peak Age of Information (AoI) is first introduced to evaluate the information and service freshness.

Age of Information for Short-Packet Covert Communication

IEEE Wireless Communications Letters, 2021
In this letter, we develop a new framework to jointly characterize covertness and timeliness of short-packet communications, in which a new metric named covert age of information (CAoI) is first proposed and then a closed-form expression for the average ...

On the Age of Information in a CSMA Environment

IEEE/ACM Transactions on Networking, 2020
In this paper, we investigate a network where $N$ links contend for the channel using the well-known carrier sense multiple access scheme. By leveraging the notion of stochastic hybrid systems, we find: 1) a closed-form expression of the average age when links generate packets at will 2) an upperbound of the average age when packets arrive ...
